What is rurema (るりま)? Japanese Ruby reference manual Rubyリファレンスマニュアル刷新計画 https://github.com/rurema rurema/doctree documents rurema/bitclust original system 3/24 

るりま != るびま Rubyist Magazine https://magazine.rubyist.net/ https://github.com/rubima a similar name, but not related in FAQ (rubima exist since that time) Q. るびま、って「ネギま！」のぱくりですか？ A. 違います。多分。「るびま」を考えた人たちは「ネギま！」 を知りませんでした (または、言われるまで気付かなかった)。 4/24 

Before rurema Before Ruby 1.4.6 https://ftp.ruby-lang.org/pub/ruby/doc/ Documents written in RD English: ruby-man-1.4.6.tar.gz Japanese: ruby-man-1.4.6-jp.tar.gz (HTML files encoding is iso-2022-jp) Ruby 1.6 to 1.8 era Edit documents on RWiki RWiki is a Wiki using RD + some extensions 5/24 

Starting rurema In Ruby 1.8 era Started rurema (Rubyリファレンスマニュアル刷新計画) bitclust supports RD based original syntax bitclust does not use RDtool (https://rubygems.org/gems/rdtool) Import documents from RWiki 6/24 

License of documents License exists in the edit form of RWiki with license can be changed if there is an agreement on ML (rubyist ML on freeml. it already removed, and freeml service ended) License changed to Creative Commons — Attribution 3.0 Unported https://github.com/rurema/doctree/blob/master/refm/doc/ license.rd 7/24 

System improvements in bitclust era Convert documents from EUC-JP to UTF-8 Support code colorize (#@samplecode) #@ is prefix of pre-processors Output as chm, ePub too may not work now if it does not work, contribution chance! default: static html (used on docs.ruby-lang.org) 8/24 

Project current status Documentation improvement sub-projects Support new versions of Ruby https://rurema-review.connpass.com/ 9/24 

Documentation improvement sub- projects Add executable sample codes https://github.com/rurema/doctree/issues/433 コピペ可能なサンプルコードを整備する Colorize sample codes → stalled (maybe almost done?) 10/24 

Support new versions of Ruby Well supported Method changes (new, changed arguments or functionality, removed) Insufficient supported Syntax changes (pattern match, &., …) Changes are not clear where to write 11/24

Future plans Short term plans Medium term plans Long term plans 14/24 

RD based → Markdown based Most important biggest short term plan Markdown is more familiar for many users It makes more contributions I am investigating how to convert from current syntax 15/24 

Current syntax #@ lines are bitclust pre-processors --- line is MethodList of RD #@since 3.1 --- intersect?(other) -> bool other と共通の要素が少なくとも1個あれば true を、なければ false を返します。 #@samplecode 例 a = [ 1, 2, 3 ] b = [ 3, 4, 5 ] 16/24 

Convert pre-processors Version branching, include, … I care about Editors support what extensions Do not break Markdown processor which does not support extensions (e.g. GitHub.com) 17/24 

MethodList What is alternative of MethodList Current syntax is based on def m(args) Blocks have notation fluctuations {|x| ... }, {|x| block }, or &block Return types are not used effectively 18/24 

Other syntax #@samplecode → code block links and references → ? (thinking) link from [[ref:m17n_prog]] to ===[a:m17n_prog] M17N プログラミングの 基本 in the same file link from [[ref:c:GC#tuning_gc]] to ====[a:tuning_gc] チューニングのた めの環境変数 in the other file 19/24 

Other short term plans and problems Clean up unused files, old files ChangeLog, setup.rb, … Not sure if tools are still usable Lack of usage documentation This is most important for contributors Reproducible build in container? devcontainer? 20/24 

Medium term plans with other software Cooperation with RBS e.g. Check signatures Cooperation with IRB Support to show rurema instead of rdoc 21/24 

Medium term plans for documents Executable sample code using WASM hanachin already tried https://github.com/hanachin/bitclust/commit/ 1ae60bfabd09c0d241e6966a6800e27a797ce175 and will discuss at https:// github.com/rurema/doctree/issues/2730 Clean up unbundled libraries and old documents Some documents moved to https://github.com/rurema/historical-documents 22/24 

Long term plans I18n support Hard to merge rdoc, so rurema will continue separately gettext based? or something else based? It should be based on English, so unlikely to come true 23/24 

end Short term most important plans to increase contributions RD based → Markdown based Improve usage documentation Middle term plans: Improve for users Resolve many historical problems progressively Contribution welcome!
